Overall, Flanagan's Wake was definitely worth it, and I probably will go back. I went with my girlfriend and we did enjoy it, however, I wouldn't recommend it to someone that doesn't like to be singled out during a show. If you are that type of person and still want to see it, I highly recommend getting tickets that are in the center of the center section (it's a lot easier for them to pick on the people on the edges of sections).
Basically, a lot of fun.
